MAGAZINE-CAMERA.

SPECIFICATION forming part of Letters Patent No. 707,156, dated August 19, 1902.

Application filed August 31, 1901. Serial No. 73,905. (No model.)

To a/ZZ zoll/0711, it' may concern:

Be it known that we, WALTER GEORGE PERES and HENRY GEORGE MEREICK FLETCHER, subjects of the King of Great Britain, residing at Hayle, in the county of Cornwall, England,have invented certain new and useful Improvements in Magazine-Oameras, of which the following is a full and complete speciiication, such as will enable those skilled in the art to which it appertains to make and use the same.

rlhe object of this invention is to provide improved means for separating exible sensitized films in a magazine-camera, said films being usually held in a pack in the camera; and with this and other objects in view the invention consists in a magazine-camera constructed as hereinafter described and claimed.

In the drawings forming part of this speciiication, in which likeletters of reference designate corresponding parts in the several views, Figure l is a central vertical section of a part of a camera provided with our improvement. Fig. 2 is a similar view showing the parts of the apparatus in a'ditlerent position. Fig. 3 is a portion of a section at right angles to that shown in Figs. l and 2 and looking forward. Fig. 4 is a similar view showing the parts in a diierent position. Fig. 5 is a side and opposite end view of the details of the construction, and Fig. 6 a similar view showing a modified form of construction andy showing a side and end view thereof.

In the practice of our invention we provide a separating-disk A, which may be of steel or other hard material and which may also be made in various shapes, (shown in Figs. 3, 4, 5, and 6,) and in one edge of this disk is preferably formed a triangular space forming a straight radial tooth or shoulder a, similar to a ratchet-tooth, beveled or sharpened on one side, so as to form an edge,which is bent backward slightly or equal to the thickness of the films to be separated. In Fig. 5 is shown another form of this disk composed of a ilat piece (marked A2) having a ratchet-tooth or projection a, the same as hereinbe'tore described, also a second piece or disk (marked AX) and an intervening disk, (marked A2,)

5o which latter may be attached to A or Ax or may consist of an independent piece, and all of which are iirmly attached to the axle B.

In Fig. 6 is shown at AS another form of disk A with merely a slit formed in the perimeter thereof, the part a2 being stamped or bent rearwardly and being also beveled or sharpened.

Referring to Figs. l to 4, the axle B is mounted in a frame C, secured to the under side of the top of a camera, near the rear end thereof, and said camera is provided at its rear end with a hinge-door A, the top and bottom portions of said camera being designated by the reference characters A5 and AG. Mounted on the axle B and working loosely on the same between separate parts of the frame C is a disk E, provided with a pin D, which operates in the hole or slot a3 in the edge of the disk A. The axle B is also provided with a cam composed of two parts H and II', the part H being connected with the frame O and being provided with an arm J, upon which acts a spring K, which controls to an extent the movement of the axle B and insures its being held in a correct position. The axle B is also provided with a spiral spring L, which exerts a pressure on the camhead H.

Passing through the top of the casing of the camera and vertically movable therein is a slide G, composed of anysuitable opaque material, and said slide is provided at the lower end thereof with a thickened portion g, which tits in a transverse cavity or recess g2 in the bottoni of the camera-casing, and the rear face of the said slide is provided at the bottom thereof with a thickened portion g, in which is formed a bayonet-slot F in such position that as the slide is pulled up the pinD enters said bayonet-slot and comes in contact with the bottom of said slot and causes the disk A and axle B to revolve to the required extent, as shown in Figs. l and 3, and the frame C is also provided with stops .l." and T2 to prevent the axle B from revolving toofar.

Iivoted to the opposite sides ol' the casing of the camera, as shown at P, are two levers O, and these levers are provided with edges which are adapted to bear against the shutter G when said levers are in an upright position, thus leaving a suitable space between the slide G and the body portions of said levers to receive the film, said lm being shown at Min Fig. 2. The lower ends of the levers O are loosely connected at O2 with a horizontally-movable slide O3, and these levers when the slide G is in its raised position, as shown in Fig. l,are normally held in the forwardlydirected position bya double spring O4, which operates in connection with lugs or projections O5, formed on or secured to ears O6, through which the pivot-pins P of said levers pass. When the slide G is depressed, the bottom portions of these levers are moved forwardly thereby and the slide O3 moves with them.

In the back portion of the camera-casing is placed a follower S, the upper end of which is provided at each side with a pin S2, and these pins rest on guide-strips S3, and similar guide-strips S4 are placed below the guidestrips S3 and serve to guide the follower S and hold it out of contact with the sides of the casing of the camera, and between the follower S and the back portionor hinged door A4 of the camera-casing is placed a spiral spring N, which forces the follower S forwardly. The front lower edge of the follower S is beveled backwardly, as shown at S5, and the pins S2 support the follower and prevent it from dropping onto the slide O3. The slide G in its operation passes through the slide O3, which is provided with an opening for this purpose, and the object of this slide is to prevent the iilms M from creating too much friction on the bottom of the casing of the camera. i The lms then are placed in a pack in the position shown in Fig. 2,between tle follower S and the slide G, and rest on the slide O3, and in operating the apparatus the said slide G is pulled up, as shown in Fig. l. In this operation the pin D will engage the groove F in the bottom of the said slide and will revolve the disk A, causing the tooth or proj ection a., which is provided with a knife-edge, to en ter the space between the first .film and the remainder of the pack and to separate the first film from the said pack. In this operation the lever O assumes the position shown in Fig. l, and the first film M drops forwardly, as shown in said iigure, and after the slide G is depressed the separating-disk A :resumes its iirst position, or that shown in Fig. l, and as the slide G descends and passes into the position shown in Fig. 2 the levers O also assume the position shown in Fig. 2, and the rear edges thereof press against the slide G and the film M rests on the shoulder or projection g4 at the bottom of said slide, and all the parts, including the slide O3, will also assume the position shown in Fig. 2, and the iilm M is in position for exposure. On again raising the slide G the shoulder or projection g4 at the bottom thereof will throw up or lift the film M', which is thrown into the compartment Z at the top of the camera-casing, said film being guided recare into this compartment by a working spring W, secured to the bottonrsurface of the camera-casing and so formed as to bear on the front pieces of the slide. The compartment Z is provided with an opening at Z2, at the bottom of which is a curved plate ZS, which also serves to guide the film h thereinto. Secured to the bottom of the top of the camera-casing are springs W2, and these springs when the said slide is drawn upwardly also strike on the shoulder or projection gfL and prevent the said slide from being withdrawn from the casing. When the slide G is depressed, as shown in Fig. 2, the spring L on the shaft or axle B is depressed; but when said slide is ymoved upwardly, as shown in Fig. 1, this spring is expanded and forces the disk A forwardly,th us enabling the apparatus to operate, as hereinbefore described.

The disks A2 and A3 (shown in Figs. 5 and 6) will operate in the same manner as the disk A, (shown in Figs. l to 3, inclusive,) and our invention is not limited to the form of the slide G nor to the various parts thereof, as many changes in the form and construction of this slide, as well as in the form and construction of the other parts of the apparatus herein shown and described, may be made Without departing from the spirit of our invention or sacrificing its advantages.

Having thus fully described ourinvention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a magazine-camera comprisinga casing, a vertically-movable slide mounted therein, a follower mounted rearwardly of said slide, an axle mounted above said follower and a separating-disk connected with said axle and means whereby the axle is turned in opposite directions as the slide is raised and lowered, substantially as shown and described.
